| Purpose | PHPUnit is a testing framework for PHP. | pytest is a framework for writing small, readable tests that can scale to complex functional testing for applications and libraries. |
| Security | The getting-started page links to documentation for verifying PHPUnit PHAR releases. | The project asks users to report suspected security vulnerabilities through a new GitHub security advisory instead of creating an issue. |

In their own words
PHPUnit
PHPUnit is a free testing framework for PHP, with a command-line runner for running tests and selecting test suites. It covers assertions for return values, exceptions, side effects, output, files, JSON, XML, and error-log output. Tests can be organized through filesystem structure or XML configuration and can use data providers, dependencies, stubs, and mock objects. The framework documents code coverage reports in HTML and JSONL formats, plus JUnit and TeamCity logging configuration. For tests that fail intermittently, PHPUnit supports repeating and retrying runs through attributes and command-line options. Installation is available as a PHAR or as a Composer development dependency. PHPUnit 13 is the current stable major version and requires PHP 8.4 or later. Bug-fix support for that version runs through February 4, 2028; its end-of-life date is undetermined. Documentation is available for versions 8.5 through 13.4. PHPUnit supports Linux, macOS, Windows, and self-hosted use.
